What kind of camera are you using?
I really think that they are nice shots, just the exposure settings were not right. I do not care for how yellow-oriented they are, although that is in some people's taste.

all this picture i modified to my own taste.
the first two pictures were exposure was fine. i just made them look like that to make them abit interesting. i don't know if it worked though.
and i'm using a sony cyber-shot

You have a tripod? Some kind of stable base is your best friend for shots like this. I like the 4th one best I think, but the first 2 look soft to me. I would also play with the white balance a bit, but that is a matter of taste since a lot of what I am seeing came about in post processing it sounds like.

the second one of the both the fountain and the car were the better ones. first fountain one couldn't really tell what it was. first car one was just really eerie so i guess if that's what u want then it works.
